APPARATUS FOR TREATING NOXIOUS GASES.

Specification of Letters Patent.

Patented June 25, 1907.

Application filed May 28,1902. Serial No. 109,403.

To ctZl whom it may concern.-

Be it known that I, ALBERT C. DAY, a resi dent of the town of Saugus, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Apparatus for Treating Noxious Gases; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to an apparatus for destroying noxious gases, and has for its object the collecting and destroying of the fumes of noxious gases received from garbage or other sources by subjecting them to a high degree of heat.

-The invention is fully described in this specification, and the accompanying drawing illustrates a diagrammatic view of the apparatus.

In the construction, A, is the receiving chamber, cylindrical in form, and preferably set on end; it is surrounded by a jacket of which a and 5 form the outer and inner walls. Steam and water are alternately admitted into the jacket for the purpose of heating and cooling the gases therein contained and is hereinafter more fully described.

C, for the purpose of illustration, represents a series of separator tanks in which garbage is treated, and from which the noxious gases are drawn by the vacuum pump D, through the pipes d and check valve R, being forced by said pump through pipe 6, which is also provided with a check valve M, into the receiving chamber A. Pipes I are provided to draw liquids from tanks C.

E is a water tank connected with the receiving chamber which supplies the cooling medium to the jacket through the pipe f, and valve Z. The pump F takes the water from the jacket and returns it through the valve 7),, and pipe g, to the tank E. The

boiler G supplies the steam to heat the receiving chamber through the steam pipe 71., and valve 1c, and also supplies the power which drives the various pumps and other machinery used in my apparatus.

H, is a chimney in the base of which is a series of flames I, burning from corresponding gas jets j, which may be automatically extinguished when not in use and lighted again when desired, by mechanism not shown.

For the purpose of illustration, let it be supposed that the gases to be treated are those collected by the vacuum pump D, fiom the garbage separator tanks, C, which are illustrated in the drawing. In preparing the chamber A, to receive the gases it is first necessary to force out a portion of the air, and I therefore heat it, by opening the valve Zr, in the steam pipe h, allowing the steam to flow from the boiler G into the jacket. This heat expands the air in the chamber causing pressure to be formed and a portion of the expanded air to pass out through the pipe J, and the opened gate valve i, into the chimney. After the heat has been allowed to continue a sufficient length of time, the gate valve i, and the valve it in the pipe 7b are closed. The valve Z, in the pipe f, is then opened and the water from the tank E, is a lowed to flow into the jacket and caused to circulate around the chamber by the spiral conductor K, cooling it off, and thereby contracting the air remaining and producing a partial vacuum in the chamber. The valve m, in the pipe (2, is then opened and the nox ious gases flow through the pipe 6, into this chamber which has been prepared to receive them as previously described. The pump D is started to assist this flow and to compress the gases in chamber A. After all the gases which the chamber will receive have been forced into it, the valve m, in the supply pipe 6, is closed and the water from the jacket is pumped out by the pump F, and forced back into the tank E. The heat is now applied again, and the gases contained in the chamber expanded, and are forced to pass out as beforethrough the pipe J. The illuminating gas in the jets j, is lighted in the base of the chimney, and as the noxious gases pass up through the bed of flames I, on their way out the fumes are completely destroyed. The operation of expanding, burning, and contracting these gases may be repeated indefinitely.

It is quite obvious that in lieu of heating and subsequently cooling tank A to draw in the gases, that said gases may be forced into said tank by pump D alone, and that the heating beconfined to the final step of expanding the gases to force them out of tank A through pipe J into the chimney.

Having thus described my invention, what I claim as my improvement and desire to secure by Letters Patent, is:

1. In an apparatus for the purpose described, the combination of a chamber for receiving noxious gases, a chimney, means for heating said gases in the base of said chimney, means for expanding the gases in said chamber and forcing them through said heating means, substantially as described.

2. In an apparatus for destroying the fumes of noxious gases, the combination of a receiving chamber, means for supplying said chamber with noxious gases, means for heating and cooling said chamber for the purpose of expelling and drawing said gases into the chamber, heating means throughwhich the gases must pass for destroying the fumes, substantially as described.

In an apparatus for destroying the fumes of noxious gases, the combination of a receiving chamber, means for supplying said chamber with noxious gases, means for heating and cooling said chamber for the purpose of expelling and drawing gases into the chamber, a chimney, heating means in the base of said chimney, a conductor pipe for carrying the gases from the tank into the chimney be low said heating means, substantially as described.

4. In an apparatus for the purpose described, the combination of a receiving chamber surrounded by a jacket, means for supplying steam and water to said jacket, a chimney, heating means located in the base of said chimney, a conductor pipe for transferring the expanded gases from said chamber to said chimney below said heating means, substantially as described.

5. In an apparatus for the purpose described, the combination of a receiving chamber surrounded by a jacket, means for causing a circulation of the heating and cooling medium in said jacket, means for supplying the heating and cooling medium to said jacket, a chimney, heating means in the base of said chimney, a conductor pipe for transferring the expanded gases from said chamber to said chimney below said heating means, substantially as described.

6. In an apparatus for destroying fumes of noxious gases, the combination of a receiving chamber, means for supplying said chamber with noxious gases, a jacket surrounding said chamber, a spiral conductor in said jacket, a boiler for supplying steam to said jacket, means for supplying water, and removing .it from said jacket, a chimney, means for heating said gases located in the base of said chimney, a pipe for conducting the expanded gases from said chamber into said chimney below said heating means, substantially as described.

7. In combination, separator tanks, pumping mechanism for drawing the noxious gases from said separator tanks, a receiving tank, means'for expanding the gases contained within said receiving tank, and means for conveying said expanded gases from said receiving tank to a point where they are con-- sumed.

8. In combination, a receiving tank adapted to be alternately heated and cooled to create a partial vacuum therein to draw the noxious gases into said receiving tank, and means for conveying the said noxious gases from said receiving tank to a pointwhere they are consumed.

9. In combination, a receiving tank, a jacket surrounding said receiving tank into which cooling and heating mediums are alternately forced to create a partial vacuum Within said receiving tank to draw the noxious gases into said receiving tank, and means for conveying said noxious gases to a point where they are consumed.

10. In combination, separating tanks, a receiving tank, means for conveying the noxious gases from the separating tanks to the receiving tank, and means for heating the receiving tank to force said gases to the point where they may be consumed.

In testimony whereof, I have hereunto set my hand this 19th day of May A. D. 1902.
